UK WEATHER forecast scorching sunshine and a new record has been set after Wales reported highs of 27.4C, August’s highest for the latter part of the month.

Gogerddan, near Aberystwyth, recorded 27.4C today which is a new record for the highest late August bank holiday weekend temperature the Met Office said. The balmy weather will only get hotter tomorrow, with it expected to sizzle to 33C. This, the Met Office said, is due to a mass of boiling hot air being pushed towards the UK via a jet stream from the Baltic’s. Britain’s positioning underneath the jet stream has resulted in the UK becoming its own “tropical” continent practically overnight.

“High pressure centred over the Baltic is bringing a tropical continental airmass to the UK and this will continue to drag hot air northwards over the next couple of days.”

The heatwave is set to last as far into the year as of October, which could mean this autumn may be the hottest on record.

But amid the heat there will also be thunderstorms, forecasters have warned.

With temperatures around 15C higher than normal for the end of August, tropical conditions will hold out through the start of next week ahead of a monsoon deluge which threatens to put swathes of the country back on flood alert.

Southern Britain will swelter in the highest bank holiday temperatures although the mercury will rocket around the country.

Exacta Weather forecaster James Madden said: “The hot spell is about to hit and over the coming day's temperatures will soar well above average for the time of year. Parts of the country will see maximum temperatures in the low to mid 30Cs at times through the bank holiday and during the early part of next week.
